    finite element analysis of briquetting of iron ore fines

    Jul 15, 2019 · Iron ore fines need to be enlarged for better handling and transportation but also for increased permeability in the blast furnace. Briquetting is a continuous compaction process to consolidate powders into a block or briquette . In briquetting, ore fines are drawn to two counter-rotating rolls and densified by high pressure from the rolls

    During the briquetting process, the exhaust port of the feed hopper on the briquette machine should be connected with dust removal pipes to make the gas discharged. During the briquetting process, the new materials must be proportioned with some crushed and returned materials, if the returning materials are inadequate, it will be difficult for briquetting, especially for the materials hard to form briquette

    The schematic represents the HBI briquetting process. Direct Reduced Iron is discharged hot from the reduction furnace and screw-fed into the nip between two counter rotating rollers. Pockets in the synchronously rotating rollers form the briquettes. This process occurs at high temperatures (typically approx. 700 °C) and high pressing forces
